The present invention relates to a user authentication method using a one-time connection code. The user authentication method comprises: a first step (S1) of connecting, by a portable terminal (10), to a server (20) over a wireless communication network, and requesting, by the portable terminal (10), a one-time connection code; a second step (S2) of verifying, by the server (20), validity of an authentication number for the portable terminal (10), and generating, by the server (20), the one-time connection code; a third step (S3) of temporarily storing, by the server (20), the generated one-time connection code in a database; a fourth step (S4) of enabling the one-time connection code to be output by transmitting the one-time connection code to the portable terminal (10); a fifth step (S5) of logging in to the server (20) by using a connection terminal (30) by combining the one-time connection code, output to the portable terminal (10), and a password together and inputting a result of the combination; a sixth step (S6) of verifying validity of the combination of the password and the one-time connection code, and transmitting a confirmation request to the portable terminal (10); and a seventh step (S7) of confirming or cancelling the login of the connection terminal (30) to the server (20) based on conformation or cancellation of the portable terminal (10). Accordingly, provided is an effect of enabling security and convenience to be improved. |
